I dont know how to get the current offset of file. about imhex HOT 7 CLOSED

Hi
Could you please clarify your question a little? What offset do you mean?

from imhex.

current byte offset of file when used in a hex pattern
hopefully that makes more sense

from imhex.

I was having the same usability issue I think: there doesn't seem to be a good way to get the current byte offset under the cursor in various views. For example, in the hex editor if I'm looking at a byte I literally counted the byte columns from the start of the row to manually type it in the pattern editor. Having every single byte offset be easily accessible would be super useful (imgui makes this nice - a byteOffsetText() fn that handled right clicking/shift+clicking/etc on the text to copy to clipboard would be easy to slot in, etc).

That is correct ^

This is possible now using the $ operator

Reference in new

can you be more specific on how to use the $ operator?

from imhex.

To copy the offset on the hex editor view place the cursor on the data whose offset you want and right click Copy As > Address. That will copy the offset to the clipboard. The $ operator in the pattern language is the operator that returns the current offset that the pattern is processing. When you place a pattern in the data using the @ operator, the value of $ is updated automatically. $ can be read, assigned to variables, written to using values or variables like for example:

std::print("{:#x}",$); //prints offset in hex
u32 offset = $;  // assigns offset to variable 'offset'
$ = a==0 ? 0x25 : a; // if a is zero set offset to 37 else set it to the value of a
